Why Honda uses lithium batteries instead of Ni-MH in the Accord hybrid? Advantages of Ni-MH batteries: When Toyota is researching hybrid systems, lithium batteries are still expensive, Ni-MH batteries are cheap, and Ni-MH batteries are in shallow charge and discharge conditions. With long service life, Ni-MH batteries are safer than lithium batteries. In addition, nickel-metal hydride batteries are more environmentally friendly in the process of processing: lithium batteries have a higher energy density, the same battery capacity is manufactured with a smaller volume and weight, the use of new cars and low weight to achieve energy saving, and agreement with hybrid vehicles An important source of power, the speed is lower than 80, the motor power is driven by the motor, and the high demand for instant charging and discharging, the lithium battery is more capable of this job, the disadvantage is that the Honda hybrid system is more expensive, and the later maintenance price is more expensive. The lithium battery is according to the shape It can be divided into laminated type, button type, cylindrical type, etc. The battery capacity and standard are different, and the size is also different. Regarding any type of battery, the folding of the positive and negative electrodes, which is the key to the manufacture of lithium batteries, is used in a larger area. From the electrode sheet to the battery, the manufacturing process differs depending on the shape of the battery. However, the distribution method of the active material, conductive agent, binder and other pastes of the positive electrode and the negative electrode, as well as the production process of the electrode sheet (that is, the upstream process), are all the same.
